The organisation says it affects 135 million globally, and these cases, along with so-called honour killings, should be treated as human rights crimes by governments.

The report highlights several individual cases, such as Kavira Muraulu, from the Democratic Republic of Congo.

Kavira, a farmer in her 50s, is from North Kivu province. She was raped and then attacked again when she complained, the report says.

'Tackle abuse'

Ms Khan said Amnesty wanted to tackle abuse in areas of war and conflict as well as the domestic arena.
She said: "As a human rights organisation we will mobilise our members and supporters around the world. Men must play a crucial part if we are to end violence against women.

"Violence is not normal, legal nor acceptable and should never be tolerated or justified. It can and must be stopped."

The report and campaign come ahead of International Women's Day on Monday.
